EXECUTIVE SUMMARY

Every business organization big or small has its own sets of problems.

Sometimes they enjoy advantages over others; sometimes they also have to bear the

heat of the competition. They are not above the ups and downs of the business.

Decimin Control Systems Pvt. Ltd deals in DG sets and acoustic system. As recently

CPCB and Ministry of forest and environment have implemented guidelines for noise

pollution. As per the regulation it is mandatory for all the users to have noise limit up

to 75 dBA. The main objectives of this study is to find the potential for acoustic

system for DG set in Pune region also to find level of awareness of pollution control

norms for noise pollution among the users.

For this purpose we have prepared a questionnaire targeting the industrial users. I

have visited the maintenance in charge of the company to find out the details of DG

set and awareness of pollution control norms for noise pollution.

The data collected from the survey was scientifically analyzed and implemented by

company. Based on these conclusions and managerial theory we recommend a set of

activities to be implemented by Decimin Control Systems to be the market leader in

acoustic.

RESEARCH METHODOLOGY

A research design is the arrangement of condition for collection and analysis of

data in a manner that aims to combine the relevance to the research purpose with

economy in procedure. Research design is the important because it facilitates the

smooth sailing of various research operations, thereby making research as

efficient as possible yielding maximum information with minimal expenditure of

minimum time, effort, money.

The research design chosen for the project was DESCRIPTIVE RESEARCH

DESCRIPTIVE RESEARCH studies are that studies that are concerned with

describing the characteristic of a particular individual, or of a group. In descriptive

the researcher must be able to define clearly, what he wants to measure and must

find adequate methods of measuring it along with a clear cut definition of

population he wants to study. The research design must make enough provisions

for protection against bias and must maximize reliability, with due concern for the

economical completion of the research study.

30

SOURCES OF DATA:

I have done the project by taking both the Primary and Secondary data.

Primary data:

The data which I have collected from different consultants and MSRDC

through questionnaires

Secondary data:

The data which is given by the company and I also searched the data

through the area wise telephone directory and field search. The data is all about

regarding the address and contact numbers of the consultants, MSRDC, Airports etc.

QUESTIONNAIRE PREPARATION:

RESEARCH INSTRUMENT:

I used questionnaire as research instrument to collect the requisite information

for the research. Questionnaire method was chosen because of its versatile.

Almost every market problems involves people. Therefore ideas relative to people and

its solution can be obtained by asking them about their problems.

This type has the advantage that the respondents do not know exactly what is being

measured and hence are not biased their answer to some extent. My research design

made it necessary for me to collect accurate data to achieve useful result. For this

reason I have decided to use primary source of data as well as secondary data.

31

DESIGNING OF QUESTIONNAIRE:

Questionnaires are designed to assess requirement and company’s need for

Acoustic Barrier. So while designing the questionnaire we have to identify who are

the probable customers of the product. But my main objective was to create the

awareness of the company so that questionnaire was designed according to gather data

and find out the prospective consultants and Organizations.

SAMPLING

Target population

Entire consultants of MSRDC, MSRDC, Road Builders, Pollution Control Board,

Railways and Airports in Pune & Mumbai Region.

Sampling method:

Convenient sampling

SAMPLE PLAN:

A proper sampling plan is very important in the research process and it also

makes the research process easy. It includes the sampling element, sample size and

sample area.

a) SAMPLE ELEMENT:

It includes those respondents who are going to fill up and answer the

questionnaire.

32

b) SAMPLE SIZE:

I have worked on a sample size of 27 including all the consultants and

Organizations.

c) SAMPLE AREA:

My main task was to collect the business related information from the

consultants and MSRDC for the company.

My area: Pune & Mumbai.

Tools used for data presentation

---- Pie charts

----Bar charts

CONTACT METHOD:

Personal as well as telephonic interview methods were used.

Personal Interview : A person known as interviewer asks question in face to

face contact to the other person.

Telephonic Interview : This method of collecting information consists in

contacting respondents on telephone itself.

The chief merits of such a system are

It is more flexible than other methods.

It is faster than other methods.

It is cheaper than personal interview.

Recall is easy.

There is higher rate of response.

Airports, Railway Bridges etc., in which barriers can be reduced to

reduce noise across the buildings, hospitals etc.

between two screens.

7 % of the respondents operated in the field of manufacturing &

operations and they wanted the sound to be reduced emitted by the

machineries.

30 % respondents were in the area of construction of roads etc, but

extent.

16 % of respondents were a part of MSRDC and were interested in

using Acoustic Barriers over all flyovers in Mumbai & Pune, barring

the Worli- Bandra Sea Link as the flyover goes over the sea and there

is no residential, commercial areas etc.

Acoustic Barriers without affecting in its performance.

42

chances of Aluminium & Steel Finishes to be stolen were high.

Polyester Powder coating Acoustic Barrier was given most preference

by the respondents i.e., 18 %.

reducing the noise while 26 % didn’t think so as most of the flyovers

LIMITATIONS

Inadequate information: Many Corporate did not reveal business related

information like their competitors, the new projects, so due to which some of

the questions were not answered/filled properly or accurately.

Due to limitations of Secondary data, many consultants who work for many

NTPCs , industries, many projects etc., were not being found out.

Sample size: As a number of respondents in Pune & Mumbai were widely

spread all over the city, so it was difficult to cover all the areas in such a short

span of time so for the convenience I took 27 as my sample size.

Many respondents could not give sufficient time to answer/fill the

questionnaire.

Due to rainy season during duration of my project it was very difficult to

approach the corporate; as a result I was short to visit no. of corporate in a day.

Some of them asked why should they give information and they are afraid to

give the information because if the company mis utilize the information.

The address of many respondents had changed, so it was difficult to contact

those respondents.

As I was not given any information on price by the company so some of the

respondents didn’t entertain me as they wanted to know first the price of the

barrier.

The Railway Authority & the Airport Authority were mostly reluctant in

giving any information.

44

Many of the respondents were reluctant in giving any appointment so were not

able to be interviewed.

RECOMMENDATIONS:

The interpretation of data revealed certain factors and problem which would affect the

future growth of the company (as stated earlier).

Recommendation regarding to above found problem are as follows:

The Data base should be updated in such away that the

customers receive the required information immediately.

The customer should be made aware of the latest developments

by issuing pamphlets, brochures etc.

The company should try to aggressive marketing by advertising

its product like Acoustic Barrier & Louvres which has less

market share.

The company should participate in the various trade shows related

to Acoustic Barrier, organized by various associations & try to

educate and create awareness among the customers across all

cities including Pune, Mumbai etc. Renowned people should be

invited to give information regarding Acoustic Barrier to the

customers.

45

The company should do a proper data base of consultants in

Power Plants, Automobile industries etc.

The Company should get information about concerned Authority

regarding Sewage Plants, road building Authority, Railway

Authority, Airport Authority etc and introduce the concept of

acoustic Barrier.

Decimin Control Systems should make efforts for its Brand

building. A established brand is very useful for a company in the

long run and helps to face competition.

Price of Acoustic Barrier, Louvres should be reduced since it is

the core product. Reduced price will also assist in competing with

other player.

Decimin Control Systems should increase the number of dealers

to expand the business. The dealers should be located uniformly

all over the Pune region & Mumbai region in order to tap and

exploit the potential market.

The company should stress and concentrate over its advertising

and promotional activities.

The customers problems should be solved as early as possible

and he should be assured that he will not be facing the problem

in near future.

Sales Associates at least have knowledge about all products

The customer care services should be improved

It should focus on the medium and small scale business segment

as it is offering a huge potential market.

46

Decimin Control Systems should continue with its penetration

pricing strategy since due to it company has started setting its foot

in the market.

Feedback should be taken from the present clients to know

whether they are satisfied and if they have problem regarding the

services. This will certainly help to improve the overall

performance of the company.

Decimin should improve service as it is in good demand and will

be having tremendous demand in the future.

Decimin Control Systems should identify new advance

technology coming into development business and should it

introduce into the design system.

47

CONCLUSION

Although a large number of corporate subscribers are satisfied with the

services provided to them, but it needs to gear up with the procedure of billing,

services and connectivity to provide not only satisfactory but a delighting service or

else the subscribers will not be locked for a long time, due to the emergence of a large

number of competitors in the market.

Though the company is financially strong at the moment but in long terms to

maintain its position, market share and customer loyalty it needs to remove its

shortfalls.
